Abstract
An information processing apparatus is operated by externally supplied DC power. The apparatus includes an external redundant power supply device including a plurality of power supply units each of which converts AC power into DC power, a housing which accommodates a plurality of devices, a DC power input terminal provided on the housing and configured to receive the DC power from the redundant power supply device, and a power supply circuit provided in the housing and configured to generate a power supply voltage, which is to be applied to each of the devices, from the DC power received by the DC power input terminal.

An information processing apparatus which is operated by externally supplied DC (direct-current) power, comprising:
- an external redundant power supply device including a plurality of redundant power supply units each of which converts AC (alternating-current) power into DC power;
- a housing which accommodates a plurality of devices;
- a DC power input terminal provided on the housing and configured to receive the DC power from the redundant power supply device;
- and
- a power supply circuit provided in the housing and configured to generate a power supply voltage, which is to be applied to each of the devices, from the DC power received by the DC power input terminal.
A method of supplying power to an information processing apparatus, comprising:
- supplying DC (direct-current) power to the information processing apparatus from an external redundant power supply device including a plurality of redundant power supply units each of which converts AC (alternating-current) power into DC power;
- and
- generating a power supply voltage, which is to be applied to each of devices provided in a housing of the information processing apparatus, from the DC power supplied from the redundant power supply device by a power supply circuit provided in the housing of the information processing apparatus.
An information processing apparatus comprising:
- a housing which accommodates a plurality of devices;
- an external redundant power supply device including a plurality of power supply units each of which converts AC (alternating-current) power into DC (direct-current) power;
- and
- a redundant power supply circuit provided in the housing, including a plurality of power supply circuit units each of which generates a power supply voltage, which is to be applied to each of the devices, from the DC power supplied from the external redundant power supply device.
